Power Distribution Units (PDUs) evenly disperse power to servers over the entire power strip. Rack mount power strips are specifically made for server racks and mount vertically or behind mounting posts in the back portion of a cabinet. Power strips fall into two categories: standard and intelligent. While standard power strips have some features that can provide valuable information, such as fuse replacement indicators and current output displays, they must be managed in-person and on-site. In contrast, intelligent power strips provide remote power control, which allows administrators to perform a cold reboot of servers and devices and troubleshoot problems from any location with an internet connection, reducing server downtime and getting vital business functions back online quickly. Remote power products not only provide intelligent control of attached systems, they also allow administrators to leverage leading advances in power distribution, such as 3-Phase power. Three-Phase power technology is not exclusive to remote power management products, but many solutions can accommodate or incorporate it. Compared to single-phase power, 3-Phase power uses fewer circuits, provides a more balanced power load, reduces the overall number of PDUs needed to power equipment, and significantly increases available amperage into the server rack. As an example, in a traditional rack environment, (4) 20-amp circuits would be required for 64 amps of available power (assuming a maximum 80% load). In contrast, a 3-phase circuit can provide up to 51.6 amps per circuit, or more than 82 amps of available power, while only requiring 2 circuits (assuming a maximum 80% load). The cost savings of 3-Phase power is beneficial, especially since experts estimate that in the future, electricity costs could rise from current levels of 10 percent or less of IT budgets to 20-30 percent (3). Other power-related aspects to keep in mind include the number of outlets you will need, plug/receptacle requirements, and redundancy requirements.
